U.S. Representatives Ed Markey (D-MA), John Hall (D-NY), and John Adler (D-NJ) have called upon the Government Accountability Office (GAO) to launch an investigation into the corrosion of and leakage from buried piping at the nation's nuclear power plants. In their letter to GAO, the Congressmen stated that "The recent discoveries of leaks of reactor cooling water, diesel fuel, and radioactive water at several plants suggest that NRC processes must be improved to help licensees adequately manage the aging of this infrastructure to ensure the safety of the reactors and of the public." The Congressmen cite leaking pipes at such nuclear power plants as Oyster Creek NJ, Indian Point NY, San Onofre CA, Byron IL, Perry OH, Dresden IL, and Braidwood IL to make clear that this is a nation-wide problem. Hazardous tritium -- a radioactive form of hydrogen -- is very often involved in such leakage into groundwater. (However, besides such accidental, uncontrolled, and unmonitored leaks, tritium is also "routinely" discharged from atomic reactors, with permission from the Nuclear Regulatory Commission.)
